(C) Given the relation $3 \bar{x} = 2 M = 60.$From this,we can find the values of mean $(\bar{x})$ and median $(M)$:$\bar{x} = \frac{60}{3} = 20$$M = \frac{60}{2} = 30$The empirical relationship between mean,median,and mode $(Z)$ is given by the formula:$Z = 3 M - 2 \bar{x}$Substituting the values of $M$ and $\bar{x}$ into the formula:$Z = 3(30) - 2(20)$$Z = 90 - 40$$Z = 50$
